How deep should compressions be on an adult during CPR?

During CPR for adults, the recommended depth of chest compressions is at least 2 inches. This depth is crucial to ensure that effective compressions can create enough pressure to circulate blood and provide oxygen to vital organs, especially the brain and heart. Compressions that are too shallow may not generate sufficient blood flow, reducing the chances of resuscitation.

The guideline of at least 2 inches aligns with evidence-based practices aimed at maximizing the effectiveness of CPR. It balances the need for adequate depth to enhance blood flow while minimizing the risk of injury to the ribcage. Maintaining this specific depth aids in performing high-quality CPR, which is essential for improving the likelihood of survival following a cardiac arrest.

Compressions deeper than 2.5 inches may increase the risk of causing injury to the thoracic cavity or internal structures, making it less practical and possibly harmful. Therefore, adhering to the guideline of at least 2 inches strikes the right balance for effective resuscitation efforts.
